AUTOMATIC GRAIN-WEIGHER.

SPECIFICATION forming part of Letters Patent No. 410,241, datedSeptember 3, 1889. Application filed January 80, 1889. Serial No.298,041. (No model.)

To all whom it may concern: a block .9, against which the weighted end aBe it known that I, CHARLEs J.

The weight e balancesthe weightbeam, and so weight e may be adjusted according to a customaryset of gradations on the weight-beam, with the assurance that the resultwill be in accurate conformity with such adjustment.

I claim as new and desire to secure by Letters Patent-- 1. An automaticweigher comprising a scalebeam, a weighing-receptacle supported from anend of the scale-beam, and a weightbeam acting on the opposite end ofthe scalebeam and having two fulcrums at different distances from saidend, as and for the purpose set forth.

2. An automatic weigher comprising a weighing-receptacle supported froman end of a scale-beam, a weight-beam acting on the I opposite end ofthe scale-beam and having two fulcrums at difierent distances from saidend, a supply-hopper, and a partial closure for the hopper adapted tooperate at the time the weight-beam shifts from one fulcrum to theother, as and for the purpose set forth.

3. In automatic weighers, in combination, the scale-beam b, theweighing-receptacle 1, dependent from the scale-beam, the weightbeam cl,fulcrumed in frame 0 and resting on the scale-beam, and frame a,embracing the weight-beam and pivoting on the permanent pivot a", as andfor the purpose set forth.

4. In automatic weighers, in combination, hopper 19, having contractedoutlet 19, compartment 10, having contracted outlet w, spout u, adaptedto swing under outlet w, and swinging partition t in outlet 19', having3 arm 25 presented to the spout, as and for the purpose set forth.

In testimony whereof I sign my name in the presence of two subscribingwitnesses.
